UNSPSC 46191624: Nitrogen cylinder

Nitrogen gas cylinders are used to cover, purge or stir chemicals or molten metals. The gas is used to extinguish fires and for freezing of soil. It can also be used to pressurize devices or pneumatically convey chemicals, while keeping out contaminates like oxygen or water.

UNSPSC 46191624 Nitrogen cylinder is a Commodity code that maps poorly to the actual work state and local governments are buying under fire safety codes and contracts. While the code nominally identifies nitrogen as a consumable gas product, recent solicitations tagged with this code overwhelmingly request inspection, maintenance, testing, repair, and certification services for fire extinguishers, fire suppression systems, fire alarm systems, and related equipment — work that falls outside the commodity scope of a standalone nitrogen cylinder product. A narrow reading of the code would suggest procurement of nitrogen gas as a refill medium for fire suppression equipment, but the state and local market activity shows that buyers are actually contracting for the labor-intensive, regulated services that use nitrogen and other gases as inputs, not acquiring the gas itself as a line-item commodity.

The issuing bodies span counties, cities, school districts, transit authorities, and independent public authorities across Georgia, Florida, Texas, Wisconsin, Colorado, and the District of Columbia. Repeat buyers include Cobb County School District (Georgia), which posted dual notices for Fire Alarm, Sprinkler, and Fire Suppression Inspection Services (RFP P26108 posted March 26, 2026, due April 23, 2026); Pinellas County (Florida) for Fire Extinguisher and Kitchen Hood Inspection Services (ITQ 26-0334-ITQ, May 12, 2026); the City of Palo Alto (California) for Automatic Fire Extinguishing System Inspection, Testing, and Repair across 33 municipal facilities (RFQ 197145, posted June 23, 2026); and Kennesaw State University (Georgia) for Portable Fire Extinguishers and Pre-Engineered Fire Suppression Systems Services (eRFP posted April 2, 2026, due April 28, 2026). Activity concentrates in Georgia and Florida, with significant secondary presence in Texas, California, Colorado, and the District of Columbia. Representative recent solicitations include the Texas Department of Public Safety's Irving Fire Extinguisher Maintenance Services (IFB 26R0017907A, due July 30, 2026), which covers annual inspections, recharging, hydrostatic testing, and ABC, CO2, and Halon fire extinguisher replacement over a five-year term; the Hillsborough County Board of County Commissioners' Janitorial and Operational Supplies (ITB-26-00319, due July 24, 2026, estimated $765,679.84), which includes consumable fire rescue supplies for 47 operating fire stations; the Orange County Transportation Authority's Fire Extinguisher Maintenance Service (RFQ 250244, due May 20, 2026, $55,000 over two years); and the Greater Orlando Aviation Authority's Fire Extinguisher Inspection, Certification, and Maintenance Services at MCO and OEA (IFB 26332IFB, due March 23, 2026, approximately $421,331.23 over five years). This code should be monitored as a secondary signal only; the primary UNSPSC classification for fire safety service contracts lies in classes addressing inspection and maintenance labor rather than consumable products.
